Subject: scsi: qla2xxx: edif: Fix no login after app start

Patch-mainline: v5.20-rc1

Git-commit: 24c796098f5395477f7f7ebf8e24f3f08a139f71

References: bsc#1201958

The scenario is this: User loaded driver but has not started authentication

app. All sessions to secure device will exhaust all login attempts, fail,

and in stay in deleted state. Then some time later the app is started. The

driver will replenish the login retry count, trigger delete to prepare for

secure login. After deletion, relogin is triggered.

For the session that is already deleted, the delete trigger is a no-op. If

none of the sessions trigger a relogin, no progress is made.

Add a relogin trigger.
